Conclusion: The Lexmark T644n is the fastest printer yet in its price class, and it complements its raw speed with a wealth of paper-handling options, including a maximum 4,100-sheet input capacity. Text quality is surprisingly low for a laser, but still good enough for most purposes.
Pros: Exceptional performance. Excellent paper-handling, with optional 4,100-sheet maximum capacity. Private printing. Prints common file formats directly from USB keys.
Cons: Although text quality is acceptable for most purposes, it's low for a laser. Photo quality is at the low end of the range for monochrome lasers.
